Page 216 EX2300-C and EX2300 Switches Hardware Guide Before you begin installing a transceiver in a device, ensure that you have taken the necessary precautions for safe handling of lasers (see “Laser and LED Safety Guidelines and Warnings” on page 241). Ensure that you have a rubber safety cap available to cover the transceiver.
Page 217: Removing A Transceiver
Documentation Connecting a Fiber-Optic Cable on page 170 Removing a Transceiver The transceivers for Juniper Networks devices are hot-removable and hot-insertable field-replaceable units (FRUs): You can remove and replace them without powering off the device or disrupting device functions. NOTE:...
Page 218 EX2300-C and EX2300 Switches Hardware Guide WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes. WARNING: Do not leave a fiber-optic transceiver uncovered except when inserting or removing a cable.

Maintaining Fiber-Optic Cables on page 201 Disconnecting a Fiber-Optic Cable from a Device Juniper Networks devices have field-replaceable unit (FRU) optical transceivers to which you can connect fiber-optic cables. Before you begin disconnecting a fiber-optic cable from an optical transceiver, ensure that you have taken the necessary precautions for safe handling of lasers.
Page 223: Maintaining Fiber-Optic Cables
Removing a Transceiver on page 195 Maintaining Fiber-Optic Cables on page 201 Maintaining Fiber-Optic Cables Fiber-optic cables connect to optical transceivers that are installed in Juniper Networks devices. To maintain fiber-optic cables: When you unplug a fiber-optic cable from a transceiver, place rubber safety caps over the transceiver and on the end of the cable.
Page 224 EX2300-C and EX2300 Switches Hardware Guide unplugging is then absorbed by the short fiber extension, which is easier and less expensive to replace than the instruments. Keep fiber-optic cable connections clean. Microdeposits of oil and dust in the canal of the transceiver or cable connector can cause loss of light, reduction in signal power, and possibly intermittent problems with the optical connection.
